DOOR OPERATING AND LOCKING MECHANISM.

Application filed September 11, 1926. Serial No. 134,758.

The present invention relates to door operating and locking mechanism.

The present invention constitutes an improvement over the structure described and claimed in the application of Gabriel Madland and William W. Darrow, Serial No. 48,458, filed August 6th, 1925, for improvements in door operating and sealing mechanism. The present invention relates primarily to door operating and locking mechanism for sliding doors such as are used on freight cars.

An object of the present invention is to provide a simple door operating and looking mechanism which maybe readily applied to railroad freight cars as now desi ed and used and which has improved e ciency over prior structures.

A further object is to provide door operating and locking mechanism which will not only facilitate the opening and closing of a frei ht car door, but will be effective in holding said door in ventilating position.

A further object is to provide door closing mechanism having simple and effective means for holding the door in closed osition to permit the ready insertion o the latching bolt in latching position.

A further object is to provide door operating and locking mechanism which is well adapted to meet the needs of commercial service.

Further objects will appear as the de scription proceeds.

Referring to the drawin s- Figure 1 is a view in si e elevation of a part of a railway freight car having one embodiment of the present invention applied thereto;

Figure 2 is a view similar to Figure 1, but showing the freight car door held in ventilating position by mechanism embodying the principles of the present invention;

Figure 3 is a sectional view taken along the plane indicated by the arrows 33 of Figure 2, and

Figure 4 is a view similar to Figure 1 but having parts of the mechanism broken away to show means for holding the freight car door in closed position preparatory to moving the latching bolt into latching position.

The numeral 10 indicates a side wall of the car. and the numeral 11 indicates a sliding door. One ed e of the doorway for said sliding door is de ned by the door jamb indicated in Figure 3 by the numeral '12. Stationarily mounted upon the door jamb 12 is the bracket 13, which maybe secured to said jamb and to the side of thecar b any preferred means, bolts 14-14 being i lustrated for that purpose. The bolts 14-14 have semi-round heads resented exteriorly of the car. The nuts or said bolts are presented inwardly of the car. Mounted u on the sliding door 11 is the bracket 15, w ich is also supported by bolts 14-44 having semi-round heads presented exteriorly of the car, the holding nuts being presented interiorly.

The bracket 13, carried bg the jamb 12, is provided with the outstan ing in or stud 16, which has an enlarged head 1 and which forms a pivotal support for the member 18. The bracket 13 is provided with the lug 19 adapted to engage the under side of the member 18 to limit movement of said member 18 in a clockwise direction. Said member 18 is provided with the slot 20, which slot receives the pin 16. One extremity of the member 18 comprises a catch portion 21. and the opposite extremity of said member 18 comprises the latching portion 22.

Pivotally carried by the bracket 15 is the operating lever 23 having the handle por tion 24 and the operating portion 25. The operating portion 25 includes the toe 26, adapted to engage within the hooked over portion 27 of the member 18. The operatportion 25 of the lever 23 is also provided with the camming surface 28, which camming surface has a progressively increasing radius about the axis of swing of the lever 23. The stationarily mounted bracket 13 has the abutment portion 29. It will be clear without detailed explanation that counterclockwise movement of the lever 23 as the parts are viewed in Figures 1 and 2 will result in a camming action between the operating portion 25 of the lever 23 and the abutment portion 29 of the stationarily mounted bracket 13, resulting in the opening movement of the door 11. When the door 11 is open and it is desired to move said door to closed position, the closing movement may be accom lished by engaging the toe portion 26 of ,t e lever 23 within the hooked over portion 27 of the member 18. A clockwise movement of lever 23 will result in the effectual forcing of the door to its closed position. The above described functions are described and claimed in the Creer Patent No. 1,544,376.

It has been common practice in freight cars to provide a hasp fastener, a hasp fastening strap and a locking bolt. One of. the tricks to which car thieves have resorted has been to saw through the material providing the bottom part of the slot in the locking bolt in which the car seal is mounted. enabling a thief to open the car door without breaking the seal, and, after he has left the car, putting the parts back in the positions in which he found them, the saw cut being quite inconspicuous and very likely to be overlooked by the car inspectors. The present' invention provides a structure which will effectually prevent any such procedure on the part of a car thief. As noted above, the member 18 includes the locking bolt 22. Sadd. locking bolt is adapted to reciprocate in an aperture 30 provided by the bracket 13. Formed integral with the lever 23' is the projecting portion 31,. providing an aperture 32,. adapted, when the door 11 is in closed position, to register with the opening 30 in the bracket 13. Said projecting portion 31 includes the bottom: member 33 adapted. to underlie the lower extremity of the locking. bolt 22. The locking bolt 22 is provided near its lower extremity with the slot 34 adapted to register with the slot 35 in the projecting portion 31 of the lever 23 when the door 11 is in closed position. Said registering slots 34 and 35 are adapted to receive the usual sealing strip. The bottom member 33 servesto prevent the car thief from gaining access to the bottom end of the bolt 22 to perform the. sawing. operation above referred to;

By reason of. the fact that the present construction involves the use. of a single member. as a catch member for cooperating with the lever 23 and as. a locking bolt, it is advisable to provide means whereby the door 1.1 will be held in closed position independently of the member 18 when said member is being moved to a position to perform its latching functions. By reference to Figure 4 it will be noted that the projecting portion 31 of the lever 23 is provided. with the finger 36 adapted. to have hooking engagement with the lower extremity of. the abutting portion 29 of the bracket 13. It will be clear that after the door 11 has been moved to closed position, or substantially to closed position by the lever 22., the finger 36- will be in wedging position behind. the portion 29 of the bracket 13, whereby said finger 36 will hold. the door 11 from springing or sliding open. By exerting a slight force upon the operating member 23 in a clockwise direction, the operator may therefore hold the door 11 closed independently of the member 18, giving the operator plenty of opportunity for swinging said member 18 from its full line-position shown in Figure 4 to its dot-ted line position as shown in said figure.

The present invention presents the advantage that thedoor may be conveniently held in ventilating position,.that isslightly open position. By reference to Figure 3 it will be noted that the operating member 23 is loosely mounted upon the stud 16, whereby to be. capable ol a rocking movement in a direction transverse to the plane of the car side. For this PULPOHQ the stud 16 maybe tapered, the diameter of saidstud 16 decreas ing from the face of the bracket 15 toward the outer extremity of said stud 16.. The ap erture. in the operating lever 23 which receives said stud may be cylindrical in. CO1L- tour, or may be reversely tapered to the taper: of the stud 16. A washer 3T insures the re tention of the operating lever 23 upon. said stud 16. By reason of the loose connection between the operating lever and the stud 16,. said operating lever may be swung from the position shown in Figure l in a counterclockwise direction past the bracket 13 and the parts carried; thereby to the position indicated by full lines in Figure 2. The bracket 15 is provided with the. abutment portion. 38,. which,. as noted in Figure 2,. is adapted. to form a support for the operating lever 23 for holding same in the position shown in Figure2. Said operating lever 23 is provided with. the outstanding portion 39 havingv the aperture L0. As indicated in Figthe member 13 may be disposed within said aperture whereby to hold the door 11 in. open position.
